Abstract
A metal substrate provided with surface textures wherein different texture patterns are provided over predefined surface areas of the metal substrate and wherein the different texture patterns are tailored to predefined surface properties of a product which is to be made out of the metal substrate as well as to a method for applying such surface textures on the metal substrate.
Claims18
A metal substrate provided with surface textures wherein different texture patterns are provided over the surface area of the metal substrate wherein the texture pattern comprise dimples with a diameter in a range of 25-120 μm, a depth in a range of 2-12 μm and a density in a range of 100 to 10000 per square millimetre.
A method for applying surface textures on a metal substrate wherein the method comprises the steps of:
- collecting data concerning dimensions, shape, forming operation and predefined surface properties of a product which is to be made out of the metal substrate,
- applying one or more texture patterns on the metal substrate wherein the texture patterns are applied on basis of the collected data such that the product has the predefined surface properties.
